The actor spoke out against Trump in an interview with The Guardian, calling him a "xenophobic fascist." He added: "In election season, things go crazy, and the loudest voices are the furthest and most extreme."

In September, the actor mocked Trump with talk of a "Game of Thrones"-esque wall on the US northern border because Canadians are "white walkers." At this year's MIT commencement ceremony, Damon expressed a fascination for a theory that states we are living in a simulated reality created by more intelligent forms of life. He then asked: "If there are multiple simulations, how come we have to be in the one where Donald Trump becomes the Republican nominee for president? Can we, like, transfer to a different one?"

Depp, who also did an impression of Donald Trump for Funny or Die, told a reporter: "If Donald Trump is elected president of the United States in a kind of historical way, it's exciting because we will see the actual last president of the United States. It just won't work after that."

Despite the word "exciting," we don't think Depp meant his declaration to be positive at all.

Lady Gaga

Lady Gaga made her distaste for Trump known in the queenlike manner you'd expect from Mother Monster. When asked if she was a fan of Trump, she loudly chuckled.

John Oliver

"It may have seemed harmless a year ago, but now that it’s got frighteningly bigger, it is no longer wise to ignore it," he said.

It's also worth watching to see how Oliver compares Trump to a lunch buffet at a strip club, the NFL, and a pet chimpanzee.

When the BBC reported that people were comparing Trump to Lord Voldemort, J.K. Rowling couldn't let her "Harry Potter" villain be treated so poorly. She tweeted: "How horrible. Voldemort was nowhere near as bad."

America Ferrera

Trump's views on Mexican immigrants have kept him in the spotlight and ushered in a wave of responses from celebrities with Latino heritage or family members. While Ricky Martin's essay for Univision focuses on the anger about Trump's xenophobic campaign, America Ferrera's essay for The Huffington Post has a more positive connotation. She thanks Trump for energizing Latino voters to get to the polls and prove his comments wrong, and for reminding America of the antiquated viewpoints that still need to be combated in the modern era.

Tyrese

Trump's comments about Muslims have also spurred backlash from celebrities such as Tyrese. The actor and singer posted on Instagram that Trump "offended my #Muslim community, and created racial boundaries and set my people up for hate crimes and to be targeted for bigotry because of the 'acts' of some... Islam is PEACE.....THE ACTS OF SOME of ANY GROUP doesn't justify you spreading hate towards ALL of my people in the Muslim and or Arab community."

Louis C.K.

In an email to fans, Louis C.K. called Trump an "insane bigot" and "dangerous." He wrote:

Please stop it with voting for Trump. It was funny for a little while. But the guy is Hitler. And by that I mean that we are being Germany in the 30s. Do you think they saw the sh-- coming? Hitler was just some hilarious and refreshing dude with a weird comb over who would say anything at all. ... If you are a true conservative. Don’t vote for Trump. He is not one of you. He is one of him.

He also clarified that the email didn't mean he was endorsing Hillary Clinton or Bernie Sanders either: "I like them both, but frankly I wish the next president was a conservative only because we had Obama for eight years and we need balance."

The cofounder of Def Jam Recordings penned an emotional and personal essay on Global Grind about his history with Trump, asking him to "stop the bulls---" and be "the man I have known for nearly 30 years."

Jennifer Lawrence

The dystopia that Lawrence's character Katniss Everdeen knows in "The Hunger Games" is what the actress imagines as the reality of Trump's America. In an interview with Entertainment Weekly, she said that "if Donald Trump becomes president, that will be the end of the world." Her "Hunger Games" costar Liam Hemsworth agreed; "I’ll back you up on that," he said.

The rapper posted a video on Instagram with a "nonviolent but unapologetic" message asserting that no one who supports him will support Trump, though he had some more colorful words. He wrote, "I know u got plans for my people that are contrary to OUR BEST INTERESTS. ... WE AINT ON THE SAME SIDE. ... I have ancestors that I WILL NOT LET DOWN." A few weeks later, he posted a photo of Trump as The Joker, saying he is a clown for his comments about abortion.

Lena Dunham

Lena Dunham said she would move to Canada if Trump is elected and that his "condescending misogyny is now a more trademark feature than his 'do." In Time, Dunham and her "Girls"cocreator Jenni Konner criticized the way Trump talks about women:

Would you like it if your own daughter’s merits were assessed by someone like you, someone who thought her looks and her sexual choices and the very sound of her voice were fair game? Donald Trump, your lack of connection to the people you want to govern is evident in more ways than we can count, and especially glaring when you consider the divide between the woman you raised and the women you want to lead.

Lin-Manuel Miranda

The "Hamilton" creator and star spoke about politics quite a bit in his interview with Rolling Stone and had these words to say about Trump:

But I can tell you that Trump's politics about building a wall, that's old. And it's such a malignant form of a very common American electoral disease, which is, 'Point at the newest people here and say they're the reason you're broke.' That's as old as time itself. That's 'Irish Need Not Apply.' That's [Pat] Buchanan in the nineties. And it's finding purchase with Trump right now.

Miley Cyrus

Not only did the singer call Trump a nightmare, but Cyrus also created a hashtag — #aintapartyindausaanymo — to accompany a chart showing Trump's leadership in the Republican race. The butterflies aren't flying away with this one.

In an interview with TYT Politics, the actress said she believes the "sane Republicans" must be embarrassed by Trump, whom she compared to a "drunk uncle:"

He reminds me of, like, your drunk uncle at a wedding who gets up and starts talking and just loves the crowd and just goes on and on and on and says whatever he can to get a reaction ... He’s like a figure from a Kurt Vonnegut novel, you know? So I can’t even address him seriously.

Chelsea Handler

Once again, Chelsea Handler posted a photo of her body on social media to make a statement. In 2015, she went topless on Instagram to take a stand for women and parody Vladimir Putin, and in April, she posted a photo on Twitter with "Trump is a butthole" written on her back and butt to denounce the candidate. She also proudly displayed her Trump pinata and a need for a "good tree for this a--hole."

Ben Stiller

Even though Trump endorsed Stiller's Zoolander in a cameo in the 2001 film, the actor doesn't seem to think so highly of the businessman. In an interview with ABC News, he said:

I’m surprised that he’s gotten this far and that it’s gone on this long with, you know, the rhetoric that he puts out there, for sure. For me, he seems more like a villain in a ‘Naked Gun’ movie or something. I can't take him seriously. But some people are taking him seriously, which is the crazy thing ... But I don’t see it going all the way.

Rosie O’Donnell

It's no surprise that Rosie O’Donnell and Donald Trump don't get along. The two have famously feuded for years, so it's fitting that O'Donnell has tweeted that Trump is "the worst," and said she has a "DUMP TRUMP" tattoo on her butt. She also retweeted a meme of a Trumpified orange.

Sarah Silverman

Sarah Silverman never holds back, and talking about Trump is no different for the actress and comedian. She often tweets and retweets highly critical posts about Trump and refers to him as "Drumpf."

Richard Gere

The actor called Trump "Mussolini" and said he is "totally ill-equipped ... It’s kind of everyone’s nightmare that it might happen."

Mike Mills

The R.E.M. bassist called Trump "the Orange Clown" after the candidate came onstage to the band's hit "It's the End of the World as We Know It (And I Feel Fine)." Mills tweeted: "Do not use our music or my voice for your moronic charade of a campaign."

Cher

The singer proclaimed that she would move to Jupiter if Trump were elected and said she believes he would start a race war. In her very expressive tweeting style, she said: "Trump Will PROVOKE RIOTS.., Like Hitler PROVOKED… KRISTALLNACHT Sometimes'Would B Dictators' Wear Expensive Suits,&Make-Up #TrumpaLumpa."

Stephen Hawking

When ITV's "Good Morning Britain" program asked Hawking to explain Trump's political success, the renowned scientist said "I can't." He added: "He is a demagogue who seems to appeal to the lowest common denominator."

Michael Moore

The director posted an open letter to Trump on Facebook detailing their first meeting in 1998 — which made Moore think of Trump as a "wuss" — and stating that "we are all Muslim." He didn't stop there; on Twitter, Moore called Trump the "skank version of Bush."

Josh Gad

The "Book of Mormon"and "Frozen" star uses Twitter as his tool to denounce Trump. His pinned tweet says: "So we're doing this Trump thing America? Okay." along with a GIF of a man rubbing his forehead. He also likes to put his hatred of Trump in Marvel terms, tweeting: "In a world in which Trump could be president, why wouldnt #CaptainAmerica be turned into a Nazi informant? #2016, the year we lost our minds."
